SPECIFICATION forming part of Letters Patent No. 458,224, dated August25, 1891.

I Application filed May 28, 1889. Serial No- 312,417. (No model.)

To all whom it may concern/.-

Be it known that I, ALFRED S. DINSMORE,

of Boston, county of Suffolk, State of Massa chusetts, have invented anImprovement in Apparatus for Treating Cloth, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to apparatus for treating cloth, and isespecially adapted to be used in the inspection of cloth, and has forits object to construct a machine, as will be described, whereby bothsides of the cloth may be inspected at the same time from one end orside of the machine. In accordance with my invention the cloth to beinspected is preferably taken from a roll, and is first carried,preferably, in front of the lower portion of the machine and secured toa carrier, preferably a hooked bar fastened to endless chains, by whichthe cloth is carried to the back of the machine, over the top or end,and then in front of the said machine, where the cloth is removed fromthe carrier and placed about a shaft or roller, upon which it is woundby a friction roller or surface, as will be described. One side of thecloth is presented to view to be inspected at one part of the machine,and the other side of the cloth is presented to view as it passes infront of the other portion of the machine.

The particular features of my invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a front elevation, partly in section, of one form of machineembodying my invention; Fig. 2, a side elevation, partly in section, ofthe same, looking to the left in Fig. 1; Figs. 3 and 4, details to bereferred to; Fig. 5, a longitudinal section of a portion of the machineon line x as, Fig. 1, looking toward the right, parts being in elevationand parts being broken away; Fig. 6, a detail to be referred to; Fig. 7,a modification to be referred 'to; Figs. 8 and 9, details to be referredto;

Fig. 10, a section on line y y of Fig. 9, and Fig. ll a detail to bereferred to.

The machine herein shown is set upright, and consists of two side framesA A, preferably made of iron or other suitable material of sufficientstrength tosustain the working parts. The side frame A at or near itsbot tom has secured to it, as herein shown, as by bolts a, a T-shapedbracket (4, in which is journaled one end of a main shaft a having itsother end supported by the side frame A.

.The main shaft a has loosely mounted on it a treadle or foot-lever apivoted, as at at to the side frame A and preferably extended out infront of the machine. The loose pulley a is brought into engagement withthe friction-disk a to produce rotation of the main shaft by depressingthe foot-treadle. The friction-disk a has mounted on its hub a pinion ain mesh with a gear a on a shaft or arbor c4 supported by the frame A,the gear c0 meshing with a smaller gear a on a shaft c0 (see Fig. 2,)and the gear a meshes with a pinion a (See full lines, Fig.1, and dottedlines, Fig. The pinion a is mounted on a shaft a",,having at itsopposite end a small gear (1. in mesh with a gear (L19 on a shaft c0mounted upon it a clutch mechanism consisting, as herein shown, of twolooselymounted friction-disks b and I), (see Figs.- 1 and 3,) betweenwhich is located to slideon' the shaft a a hub b keyed on said shaft andprovided with disks 5 b the said hub' being provided with a groove bengaged by the arms I) of a forked lever b pivoted as at b and providedwith a suitable handle I)", which is herein shown pivoted, as at b tothe frame of the machine, the said piv'ot having an enlarged head toloosely engage the slotted end of the lever b whereby the said hub maybe moved in opposite directions to produce opposite rotations of theshaft a the enlarged head on the handle b acting. on the slotted end ofthe lever b and turning the said lever on its pivot b the enlarged headturning the slotted end of the lever in the same direction as thehandle, and thereby moving the other end of the lever 19 and the Theshaft a has hub 19 in the opposite direction to that in which the saidhandle is moved. The gear a as herein shown, is secured to the disk I),and both are loose on the shaft while the disk b has secured to orforming part of it a pinion b which is loose upon the shaft 01. and ispositively driven by the gear a, with which it is in mesh, as shown bydotted lines, Fig. 2. It will thus be seen that the gear 0 through thepinion a and gear a drives the gear a, as indicated by arrow 20, whilethe gear a at the same time drives the pinion Z9 in the oppositedirection, as indicated by arrow 21. The shaft a has its opposite endssupported in the side frames of the ma chine, and between the saidframes it has fast upon it a friction-surface, preferably a roller 1),which may be of wood or other material provided with a covering orsurface of sand-paper or other rough material. The shaft 61. has mountedupon it beyond or out side of the side frame A, as herein shown,- apulley Z2 and a gear I), the said pulley being connected by a suitableband Z9 to a like pulley 11 on a shaft I)", supported at the top of theframes AA, the upper portion of the said side frames marked B beingshown as inclined from the lower or upright portion.

The shaft 1)" has fast on it between the side frames A A a frictionsurface or roller 19 which in practice is operatively connected to thefriction-roller Z2 by the cloth to be inspected. The shaft b has looselymounted on it sprocket-wheels b Z1 which are connected by endlesssprocket-chains Z2 17 to like sprocket-wheels Z2 Z1 loose on the shaft(0 The endless chains Z9 Z1 are connected preferably by abar d providedwith a series of hooks (1 which forms with the said chains a carrier bywhich the cloth is carried from one side, as the back, to the otherside, as the front of the machine, as will be described. The endlesschains {1 13 are preferably passed about auxiliary sprocket-wheels Z7 bmounted on arms b 5 secured to the side frames A A, (see Figs. 1 and 2,)to take up the slack in the chains, which are made of sufficient lengthto be readily removed from the-sprocket-wheels on the friction-rollers.The sprocket-wheel b loose on the shaft a is rendered fast on the saidshaft, so as to produce travel of the sprocket-chains, as herein shown,by a gear 0, secured to or forming part of the sprocket-wheel 6 and inmesh with a pinion c on a shaft 0 having bearings in suitable bracketsattached to the side frames and located, as herein shown, above thefriction-roll 19 The shaft 0 is provided at its opposite end with apinion 0 which meshes with a gear 0 secured to or forming part of thesprocket-wheel I), loosely mounted on the shaft a. The gear 0 haspivoted to its face, as at 0 (see Fig. 6,) apawl 0 adapted toengage theteeth of a ratchet-wheel or gear a keyed on the shaft a The pawl c ismade,

as herein shown, in the segment of a circle, it being pivoted at itscenter and having its rear arm 0 engaged when the machine is stopped orout of operation by an arm 0 of a lever 0 pivoted as at 0 The pawl c hasco-operating with it a spring 0 which acts to throw the forward end ofthe pawl into engagement with the teeth of the ratchet-wheel 0 when thearm 0 of the lever 0 is out of engagement with the arm 0 of the pawlthatis, when the machine is in operation. The lever as herein shown, hasextended from it an arm 0 upon which is pivoted a pawl 0", adapted toengage a latch or arm 0, extended from a sleeve c ,'mounted upon a shaftor arbor 0 The sleeve 0 is provided with a handlec and also with an armextended in beneath the sprocket-wheel Z1 the said arm being provided atits end, as herein shown, with a cam or projection 0 which is adapted tobe struck by a cam or projection 0 on the endless chain 19 The sleeve 0is also provided with a depending arm 0 adapted to engage a notch ortooth cZ at the upper end of a rod d, secured to the foottreadlc a thesaid treadle having secured to it a spring d, (see Fig. 5,) by which itis lifted when the pawl 0 is disengaged from the tooth (1*. The gear 0'is preferably made smaller than the gear 0, with which it meshes, (seeFig. 11,) and has secured to or forming part of it a dog (:1 which isadapted to strike the arm 0 of the pawl and lift the latter out ofengagement with the teeth of the ratchetwheel 0 for a purpose as will bedescribed. The lever has its short arm (1 connected to a spring d", (seeFigs. 5 and 6,) by which the end 0 of the said lever is thrown forwardinto engagement with the arm 0 0f the pawl to keep the latter out ofengagement with the ratchet-wheel 0 The end of the cloth is attached tothe hooks d, by which it is carried in the machine herein shown uparound the back side of the machine over the roller Z9 and down in frontof a blackboard (1 until it reaches the starting-pointnamely, theposition shown in Fig. 1when the cloth is disengaged and laid around apreferablysmooth shaft or roller (1 havingits ends supported, as hereinshown, in brackets (1 (see Fig. 5,) secured to the side frames of themachine. The brackets (1 may also support, as herein shown, afriction-roller (Z located in front of the friction-roller I3 the rolleral being rotated in the same direction as the roller 19 as herein shown,by a gear (1 in mesh with an intermediate gear or pinion (1 (see Fig.1,) driven by the gear b on the shaft a The side frames at their lowerends, as at the front of the machine, support, as herein shown, a troughor receptacle d, mounted upon rods (Z secured to the said side framesand in which the roll of cloth (Z to be inspected is placed.

In the practice of my invention as thus far described the operator takesone end of the cloth and first carries it up to the bar d and engages itwith the hooks d thereon, the said cloth being preferably passed over ahorizon- IIO tally-inclined bar or rod d", having one end, as

cured to a bracket (Z attached to the side frame A, and having its otherend supported by a bracket (Z attached to the side frame A, and by whichbar the cloth as it leaves the roll is put under tension, the saidtension being greater at one side of the cloth than at the otherthat is,the tension of the cloth passing over the outermost end of the bar,which may be supposed to be the right-hand end of the bar in Fig. 1, isgreater than the tension upon the cloth passing over the left-hand endof the bar in Fig. 1, and as a result the roll in the receptacle or tubis drawn or forced toward the left-hand end of the said tub. It isevident that the bar or rod d" may be inclined in either direction, orit maybe straight and the tub or receptacle inclined in either directionand effect the same result. The

cloth having been secured to the cross-bar 61 is now ready to becarried, as herein shown, up the back side of the machine and down overthe blackboard (Z and to do this the operator first depresses thefoot-treadle a and through the turn-buckle a and lever a engages theloose pulley a with the frictiondisk a thereby producing rotation of theshaft a The loose pulley a is maintained in contact with thefriction-disk a by lockin g the foot-treadle in its depressed position,

which is accomplished by throwing the handle 21 of the sleeve 19 in thedirection of arrow 20, Fig. 6, thereby bringing the pawl or arm 0 intoengagement with the tooth cl on the rod (Z. The inward movement of thehandle 0 raises the arm 0 of the sleeve 0 and places the block orprojection e thereon into position to be acted upon or struck by the cam0 on the endless chain b. The lever e is now thrown back in thedirection indicated by arrow 21, Fig. 6, leaving the arm 0 of the pawlfree to be acted upon by the spring 0 to turn the said pawl on its pivotand into engagement with the ratchet-wheel c so that when the shaft a isrotated, as will be described, the gear 0 and its attached sprocketwheelwill also be rotated, and the endless chains b b made to travel, thesprocketwheel 5 being rotated through the gears c c on the shaft 0 andthe gear 0 secured to the said wheel. When the handle of the lever 0 ismoved in the direction of arrow 21, the pawl c on the arm 0 of the saidlever is moved forward into engagement with its latch e thereby lockingthe sleeve 0 in its position and maintaining the pawl 0 in engagementwith the tooth d" to keep the foottreadle depressed and the loose pulleya in engagement with the friction disk a until released by thecam-projection 0 striking the cam 0 on the arm 0 secured to the saidsleeve. The machine is now in position to be started and to producetravel of the endless chains in the direction of arrow 23, Figs. 1 and6, thereby to carry the endof the cloth up the back and over and thendown in front ofthe machine to the starting-point. The handle 12 of thelever b is now moved toward the right in Fig. 1, or in the directionopposite to that indicated by arrow 24, Fig. 3, to cause thefrictiondisk 17 to be brought into engagement with the friction-disk b,which produces rotation of the shaft a in the direction of arrow 21. Theshaft a continues to revolve in the direction indicated by arrow 21until the cam or projection c strikes the cam 0 on the arm 0 therebystopping the movement,

or travel of the endless chains, for as the cam strikes the cam 0 thesleeve 0 is turned on the shaft 0 and the pawl e disengaged from thetooth d of the rod d, thereby permitting the spring 01' to raise thefoot-treadle a and through the turn-buckle a and lever a move the loosepulley a out of engagement with the friction'disk a thereby stoppingrotation of the main shaft. When the arm 0 is struck by the cam 0 thelatch e is dropped down and out of engagement with the pawl 0", thuspermitting the spring (1* to turn the lever e on its pivot and bring theend 0 forward into engagement with the arm 0 of the pawl c to maintainthe latter out of engagement with the ratchet'wheel 0 In order todisengage the pawl from its tooth, the dog 01 on the gear 0 strikes thearm c just before the cam strikes the end of the arm a, and to effectthis result the gear 0 may be made somewhat smaller than the gear 0, sothat it will make, for instance, six complete revolutions while the gear0 is making five, the dog 61 being thus made to act on the arm 0 justbefore the cam 0 strikes the cam on the lever 0 The cloth is nowdetached from the hooks on the bar 01 and wound once about the shaft 01it being interposed between the said shaft and the friction-surface ofthe roller I). The foot-treadle is now again depressed and locked in itslowest position and the main shaft rotated. The rotation of the mainshaft causes rotation of the shaft a in direction of arrow 21, Fig. 3,the friction-disk 17 being in engagement with the disk b. 'As the shafta rotates in the direction of arrow '21 it causes rotation of the shaft(1 in the opposite direction and winds the cloth upon the said shaft,the operation being continued until the roll of cloth in the trough dhas been unwound. As the cloth passes upward in front of the machine oneside is exposed to view and can be inspected, and as it passes over thetop of the machine and down in front of the blackboard d the other sideis exposed to view and can be inspected at. the same time, and thereforefrom one side of the machine. The cloth on its passage from the roll tothe top of. the machine preferably passes over a second friction-roller6, located. as shown, below the friction-roller Z2 I have herein shownthe machine as provided with one blackboard d at its upper end; but itis evident that a second black- IOL.

board may be used in similar manner at its lower end.

If for any reason it is desired to run back a portion of the cloth woundupon the shaft (1 the handle 12 is moved in the direction indicated byarrow 24 to remove the frictiondisk 12 from the disk I) and bring thefriction-disk 11 into engagement with the disk I) to produce reverserotation of the shaft a which is effected by the gear a, which rotatesin an opposite direction to the gear b as indicated by arrow in Fig. 2.

The shaft 6 of the roller 6 may and preferably will operate a recordingmechanism 6 of any usual or well-known construction, by which the numberof yards of cloth inspected in a given time may be ascertained.

In order to obtain a substantially straight edge on the roll wound up onthe shaft (1 I have provided, as herein shown, an adjusting device, (seeFigs. 1 and 4,) which consists of a plate a having hubs e fitted looselyupon the rods (1, which support the trough, the said plate having, asherein shown, an arm 6*, to which is connected a crank e on a shaft 6,having bearings in suitable brackets 6 attached to the side frame A, andprovided, as shown, with a handle a by rotation of which the shaft 6 maybe rotated to produce longitudinal motion of the plate 6 and move theroll bodily in the trough, so that one edge of the cloth may bemaintained in contact with a guide (1 herein shown as a collar on thebar (1", whereby the said edge of the cloth is made to follow a truepath and be wound substantially straight upon the shaft (1 With somegrades of cloth, especially of fine texture, it may be found that toogreat a tension wouldbe a detriment and might injure the said cloth, andin this case the rod or bar d would be dispensed with, and the roll ofcloth might and preferably would be maintained pressed against theadjusting device by suitable springs d, which encircle the lower rods (1of the trough, as indicated in Fig. 1, the said springs being located atthe end of the trough opposite to the adjusting device and actingagainst that end of the roll.

The friction-roller b as shown in Fig. 1, is rotated continuously, andwhile I prefer to have the roller 19 rotated continuously I do notdesire to limit my invention in this respect, as it is evident the saidroller may be rotated at intervals or intermittingly, one form ofapparatus for producing the intermittent motion being shown in Figs. 7to 10, inclusive.

Referring to Fig. 7, the shaft a has loosely mounted upon it a clutchmechanism (shown as a gear f) provided with an annular groove to beengaged by the arms of a forked lever, as b the said gear having securedto or forming part of it friction-disks f f, adapted to be brought incontact with two disks f f, loose on the shaft C620 and provided withinclined notches or recesses f on their peripheries, as clearly shown inFig. 9, the notches f of one disk, as f being inclined in an oppositedirection to the notches of theother disk f The inclined notches orrecesses have located in them small rollers f which are kept in place byannular rings f f", secured to or forming part of disks f, fast on theshaft a The gear f meshes with a-toothed segment f on an arm pivoted, asat f and connected by a rod f to a crank on the gear a, in mesh withthe'pinion a on the shaft a The operation of the intermittent motion isas follows: For instance, the handle 17 is moved to bring one of thefriction-disks, as f, into engagement with or against a disk, as f, andas the gear (0 is rotated in the direction of the arrow thereon thesegmental arm is carried upward and will move the gear f and cause oneof the said disks, as f to be moved in such directionas, for instance,in the direction indicated by the arrow in Fig. 9as to carry the rollersup the inclined sides of the notches and wedge them between the disk andthe ring f thus practically making the disk f fast on the shaft a sothat as the gear f is rotated the said shaft is rotated through thefriction-disk f, rotation of the shaft a being continued as long as thesegmental arm f is moved upward, and on its downward movement the saidarm moves the said gear f, its friction-disk), and the disk f so as tobringthe rollers to the lowest points of the notches in the disk f andout of engagement with the band or ring f and in this case the shaft aremains at rest. If it is desired to rotate the shaft a in the oppositedirection, the handle b is moved to engage the friction-disk f with thedisk f and bring the rolls of the other gear up the inclined notches andwedge them between the said disk and band f to produce rotation of theshaft a in the opposite direction. It will thus be seen that when thegear f is moved to bring the disk f into engagement with one disk f theshaft a will be rotated outhe movement of the segmental arm in onedirection and will not be moved or rotated on the movement of the saidarm in the opposite direction.

I have herein shown the side framesAA as upright; but I do not desire tolimit my invention to an upright machine, as it is evident the said sideframes might occupy a horizontal or substantially horizontalposition-that is, the side frames might be turned into apositionsubstantially at right angles to that shown in Fig. 2 and be supportedat opposite ends by suitable legs or in any other suitable manner. Inthis case what is now the back of the machine in Figs. 1 and 2 would bethe under side, and both sides of the cloth could be inspected from oneside of the machine, for one side of the cloth will be exposed to viewas the cloth passes from the roll to the cloth-carrier and the oppositeside of the cloth will be exposed to view as it passes from over themachine back to the roll (1 The cloth-carrier herein described and alsothe device for efiecting a straight edge on the roll of cloth may beused on other machines for treating clothas, for instance, on aclothwinding machine. The endless chains are held stationary while theclothis being wound up, preferably, by a friction device shown as a shoe0, secured to an arm on the lever 0 (see Fig. 5,) and engaging theperiphery of a smooth disk 0, secured to or forming part of thesprocket-wheel 12 1.
